Wossner Standard Series Piston Kit for 250cc 2-Stroke

Elevate your motorcycle's engine performance and durability with the Wossner Standard Series Piston Kit. Engineered for 250cc 2-stroke engines, this kit delivers superior power output and extended reliability, making it an essential upgrade for serious riders and rebuilders.

Description

Experience the precision engineering of the Wossner 250cc 2-stroke piston kit, meticulously crafted to enhance your engine's power and longevity. Each piston is forged from high-strength aerospace-grade aluminum alloy, ensuring exceptional resilience under the demanding conditions of a 2-stroke engine. Wossner's commitment to performance is evident in the optimized machining, which reduces overall weight without compromising critical strength in areas like the crown and skirt wall cross-section. This results in a lighter, more responsive engine without sacrificing durability.

A key feature of this Wossner piston kit is the advanced Molybdenum Disulphite (Moly) skirt coating. This permanent, low-friction coating significantly reduces piston rock and minimizes friction, leading to quieter operation, improved performance, and extended engine life. The complete kit includes the piston, high-quality nitride-coated steel and cast rings, a robust piston pin, and secure clips, providing everything needed for a comprehensive piston replacement or upgrade. With a bore size of 74.50 mm and an oversize of +0.50 mm (actual piston size 74.43 mm), this Wossner forged aluminum piston kit is designed for a precise fit and optimal combustion in 250cc engines.
